I don't believe they
I don't believe they're doing this for free. The movie is a waste of time. It takes away from the characters and made the film a bit more interesting. People who like the film would absolutely love to see this movie again.
I don't believe they would have accepted the idea of renting the movie, as the only three people that possibly have the rights to it are the people who voted for it; and they don't even have the rights to the trailer. I also think that the nude scenes are just bad, since the actress playing her is actually a lot younger than the one in the trailer. Blech.
